[Xoom General] Err0xx:
Hey folks, this is officially my first post on the XDA forums! After having recently been converted to Android from iPhone (had all of them from the original to the iPhone 4) I can honestly say that the Android OS is amazing and I will NEVER go back- absolutely in love with my Atrix and Xoom. Love the work you guys do here, please keep it up!

Anywho, I had a question about the LTE on the Xoom- in light of the recent HTC Thunderbolt delays due to alleged horrible battery life, and the EVO 4G not having the best battery life in the phone world, what do you think the LTE upgrade will do to the Xoom's battery life? Right now, it seems to have a great battery, getting through a full days use on one charge: I just can't help but wonder if that will still be the case after the LTE upgrade. What do you think? Will it be worth getting upgraded to an LTE capable device right off the bat even though LTE isn't exactly widely available? I'm just really concerned about potential battery issues.

Hope this isn't a double post- I didn't see a thread like this yet but I guess I could have missed it.

Thanks for any insight into this question and I appreciate all that you guys do!

I'm sure you'll be able to toggle 4G on/off... but yes adding a new radio will of course decrease battery life when it's on.

Everybody knows the problem of battery draining in our beloved Cappy

I found an oldschool solution.

Drain your Cappy's battery to the end

enable gps

no battery saving mode

enable wifi

Maxed brightness

After that let it charge for the night until it's 100%

After startup it will show you 97% but its 100%.

Im with wifi for 2hr and the battery draind only 7%

Also hope that this solution is not like "thanks captain obvious"

hope it will help's u, share your findings after using this method.

Using perception 10.4 and speedmod k13b

Sry for my bad english...
[Captivate General] fitao:
I will try you old school method
[Captivate General] Miami_Son:
Old school method worked on old school NiCAD batteries that suffered from memory. New school LiON batteries do not.
[Captivate General] fitao:
Ok for me. I simply restart my sd gingerbread androïd. And my android consums only 6mA in sleeping mode.
[Captivate General] jonnyg1097:
I will give it a try and see how it goes.
[Captivate General] Miami_Son:
How is that relevant to a Captivate?
[Captivate General] jetpuck73:
I will give this a try.
[Captivate General] GSMinCT:
If you haven't done it in a while for a Li-on device it will recalibrate the charge controller, but it doesn't increase the actual chemical capacity of the battery like it would for NiCad.
[Captivate General] Miami_Son:
Draining Li-On batteries completely is bad for them.
[Captivate General] GSMinCT:
I've heard it's only bad if you leave them down for more than 12-24 hours. If you put it right back on the charger, I think it's good once in a while. That's that Apple recommends for theirs, anyways.
[Captivate General] Miami_Son:
Heat is the enemy of any battery. The lower you run it down the longer it will have to be on the charger to get back to 100% and thus the longer it will be exposed to heat. Calibrating the battery and then wiping the stats should be all you need to do. I easily get 25-30 hours out of my battery with moderate use and I rarely let it get below 30%. And if I listened to Apple I'd have an iPhone.:)
[Captivate General] GSMinCT:
Yeah, but these devices often get run down and charged. I think Apple's right on this. FYI, that's about the Macbook, which I have one, not the iPhone (don't have one of those).
[Captivate General] Miami_Son:
Here's what TechRepublic had to say about it:

Lithium ion

Of the types of batteries mentioned here, lithium ion cells have some powerful advantages. They have an energy density of 150 watt-hours per kilogram. Like NiMHs, Li-ion batteries have no memory effect. That is, they don’t lose the capacity to fully charge if they aren’t fully drained. Left on the shelf, they lose the least power. Their discharge rate, at 10 percent per month, gives them a good storage life (but they must be used within two years of manufacture). This means that you can grab one that you charged up three months ago, and it will still have about 70 percent of its charge left. If you’re maintaining a number of laptops, that’s good news.

These batteries also have some important disadvantages, however. They have a volatile chemistry. Each lithium ion pack in your laptop must have its own electronic protection circuit that protects against overcharging, over-discharging, and too-high current. Each cell of the battery pack incorporates a built-in safety vent. All three battery types have a safety vent, but unlike NiCad and NiMH batteries, which can withstand some overcharging, the vent in lithium-ion batteries is designed to disconnect the battery permanently if it ever has to be used. It does not reseal. The potential danger of this type is why Li-ion batteries come as a sealed unit including safety electronics. As a helpful part of the circuitry, each Li-ion battery provides a charge indicator. Pressing a button will cause a row of lights to be lit, indicating the charge, as shown in Figure A.

I was surprised to learn that of all the batteries, lithium-ions have the worst useful life. Though they have a slow discharge rate on the shelf, all Li-ion batteries irreversibly lose capacity over time. Even after one year, they lose the ability to be charged to full capacity. Cadex tests indicated that their practical service life is only two years. According to Cadex’ document, Batteries for Mobile Computing, “Li-ion batteries should not be stored for long periods of time but consumed like a perishable food.” On the other hand, while they don’t deliver as many cycles as NiCad batteries, they do provide up to 1000 cycles if they’re used within that two-year lifespan. They are also maintenance free. Not only do they suffer no memory effects, they don’t need to be periodically discharged and topped off. Like NiMH batteries, shallow discharges actually increase the number of cycles. Unfortunately, these cells are expensive. Keep in mind that your IT department might be better off with a smaller, rotating inventory.

As you can see, there's nothing to be gained by discharging them completely. BTW, Apple laptops have circuitry that prevents the device from discharging the battery completely to prevent damage. I'm not sure our phones have this, so their advice should not apply here.
[Captivate General] Haloruler64:
Android only lets the battery discharge to ~40%, WinMo6.5 to ~30%.
[Captivate General] Miami_Son:
The point is (was) that there's no memory effect and therefore no valid reason to be discharging these batteries completely. The "old school" method just doesn't apply here and could actually shorten the battery's life in terms of charging cycles.
[Captivate General] geokilla:
Define moderate use? I struggle to get over around 14 hours of use. Usual stuff includes 2 hours of music, maybe 50 to 100 text messages, up to 5 minute of calling (rarely make calls), and little to no WiFi or games. I do use the data network a bit, having Facebook and Twitter and stuff syncing every hour. But overall, my battery life sucks.
[Captivate General] Geezer000:
That's actually not bad for everything you describe. Remember in a smart phone the more the screen is on the faster the battery dies.
[Captivate General] Miami_Son:
And if you're syncing in a mediocre (1-2 bars) network coverage area it takes even more power than when you have 4-5 bars. I generally have about 2-3 hours of screen on-time between charges, several phone calls and texts, e-mail pushing every hour, some game playing, some BT on while in the car, some Market/web surfing and every other day I track my MTB rides with GPS while listening to music via BT. I put the phone on the charger every night, but I do carry a spare battery just in case. I wasn't getting this kind of battery performance on Eclair, though.
[Captivate General] Caliesv:
How? Did you do something to your phone for this?
[Captivate General] Miami_Son:
Yeah, I flashed to Andromeda 1.2.:D I also have the screen dimmed down, no active wallpaper, few widgets and I turn off wifi when I don't need it.

And to prove I'm not lying...
[Captivate General] centex99:
Miami,

Out of curiosity...how much time had your screen been on in that capture? (if you click on display, it'll show you screen on time)
[Captivate General] Miami_Son:
Couldn't tell you, that was from a couple weeks ago, but is typical of my usage. I usually have 2-3 hours of screen on time a day.
[Captivate General] geokilla:
Ah right, I forgot about automatic brightness. That's one of the biggest battery drains imo.
[Captivate General] kevalin:
Okay. I really, really am going to quit worrying about my battery life now.

I'm consistently getting 24 to 30 hours of "on" time on my Captivate with moderate use... which includes about 6 hours of actual "screen on" time. I probably get 5-6 hours if I stay on screen constantly. That's running Captivate 4.1.1 with the JK4 modem and Speedmod's latest kernel, K13c.

I just switched my modem to KP1 about 20 minutes ago, because, while the above combination gives me extraordinary battery life while the phone is idle (it was burning only 1% or 2% an hour), I didn't care for how quickly it sucked juice when anything on the phone was in use. I notice already that KP1 burns battery less enthusiastically when the phone is in use... and the in-call volume is better. I'll keep you all posted on how the battery does when the phone is idle.
[Captivate General] kakahoang:
it is unbelievable. you've unplugged for 1d and still have 65% left and you say you usually have 2-3 hours of screen on a day??? it means you can have 3 day and over 6 hours of screen on and about 30min of voice call??? with 2 hour of screen on you'll lose at least 30% of battery
[Captivate General] SlappyMcGee:
I think a lot of the Charging Cycle recommendations might have stemmed from Apples suggested battery maintenance.

Look at the last paragraph

http://www.apple.com/batteries/iphone.html
[Captivate General] Miami_Son:
It's a conspiracy.:D
[Captivate General] SlappyMcGee:
I must admit though I do the charge cycle once in awhile and it does help my battery life. Since offical Froyo my battery life has shorted but not by much.

My battery will last about 2 days between charges. I will charge it over night, unplug it around 5am then leave it unplugged until around 8:30pm the next day. It is normally around 35%.

I have noticed that when my phone gets down around 55% it seems to drain a lot slower. (takes longer to get to 50% then if it was going from say 80 - 70)
[Captivate General] shiftylock:
okay, so here's how my battery life has gone.

eclair before using this "old school method" (which I've been using since I got the phone. Just saying.) ~6hrs of fairly heavy use

eclair after method ~8hrs

froyo before method/clockworkmod battery stats wipe ~8hrs

froyo after method/battery stat wipe ~9hrs

Gingerbread before method ~10hrs

Gingerbread after method ~12hrs

Gingerbread after using clockwork mod and previous method ~15hrs

These numbers are all estimates, but I use my phone a lot. I must say, those of you with clockworkmod recovery should make use of them if you don't know how to delete the batterystats file. I still get better battery life out of my LG Quantum, but I get Android apps with my Cappy, and decent battery life.:D
[Captivate General] Miami_Son:
Here's some stats from the past day. Little over 2 hours of screen time, but a lot of wifi, GPS and streaming music use.

[HD2 General] detroja:
The Problem: My HTC HD2 touchscreen has progressively gotten worst over 2 months. At first, the keyboard was typing up wrong alphabets, then major function keys begun to malfunction, and later the whole screen. From XDA reviews, I found that changing Radio, WM, or Android ROM do not help.

Solution:

This instruction may apply to Tmobile USA users. In my search for a Do-It-Yourself fix, I searched internet for several days to no avail. Amazon.com sells Touchscreen and Digitizer but their results were inconsistent; the replacement also required time, skills & instruments that I do not have.

Tmobile: Tmobile (800 number) asked me to restore OS, but it did not work. They asked me to take it in the Tmobile store. The store associate looked at the phone, but they did not want to do anything with the phone as I did not buy my phone from Tmobile - they directed me to HTC or a local repair shop. Local repair shop was going to charge $100 for a repair and turn around time of 15 days.

HTC : I called HTC (888 356 2375). As the phone was still under warranty, they offered to take a look at it & repair it. HTC also mentioned that if the warranty is void for any reason, they would charge $39.00 for a triage fee and call me to confirm the repairing cost (in addition to triage fee). HTC mentioned that any illegal softwares found on the device would void the warranty.

Restore to OEM:

I had to restore my softwares to OEM as I installed a newer radio, HSPL, MAGLDR, and a custom windows ROM. To do so, following ROM was flashed :

RUU_Leo_1_5_TMOUS_2.10.531.0_Radio_Signed_15.34.50 .07U_2.08.50.08_2_Ship

Flashing above ROM restored ORIGINAL OEM radio, SPL, and Windows ROM. It also removed MAGLDR.

After restoring softwares to OEM, I sent the phone in. The repair was done by HTC without any charge. After sending the phone in, I had my phone back in 1 week - fairly quick service compared to all the other options I had at hand.

In the process, HTC kept me informed via email regularly. I talked to several HTC reps and they were very accommodating and courteous. I mentioned to HTC that my battery drains very easily. Promptly (in 2 days), HTC sent me a replacement battery for free. They mentioned that as long as the phone is under warranty, they will replace accessories ONCE for free. I will buy HTC again despite the touchscreen problem.

Immediately after receiving the phone, I installed newest Radio, HSPL, MAGDLR & my first Android NAND [HD2_Core_Droid_Desire_HD_V1.4_NAND_ONLY_LEO1024_TOUS]. The android ROM is rocking even harder straight out of box. :)

Enjoy.
[HD2 General] Azerox:
Had the same, perfect service from HTC.

Got it back in a box that said "im back" .. Took 4 weeks though.

This made my decision to stay with HTC in the future.
[HD2 General] Bashy29:
Same problem, possible not yet solved

My UK T-Mobile HD2 started this in December 2010, I found that 3 or 4 hard resets got it going, but the next day it did it again so sent to T-Mobile repair center, they stripped it put it back together. No Fault Found. Updated the firmware (well re-installed it as there was no newer version avaialble at the time and sent it back to me.

It worked a treat for 5 weeks then the problem was back. Sent away again, Firmware update. No Fault Found (T-Mobile had now released the 3.14 ROM) so I did get an update this time, again came back working. Even better this time as the new radio version allowed me to run an SD Android Build.

You know where this is going, lasted 3 or 4 weeks, same again, Back to T-Mobile Store, this time I did not try a hard reset prior to taking it in, so they could see the fault, I did one reset in store and the fault persisted as it always did after the first two or three, and then off to the repair centre again.

Its due back in the next day or two, No Fault Found!!! Firmware updated

I guess it will be going back again a 3 to 5 weeks.

Perhaps I should drop an e-mail to HTC to see if they can help.

Do you know what they did to yours, did they replace anything?

Cheers Bashy...
[HD2 General] Azerox:
My display was soo broken that an firmware upgrade didnt help, not even for a second.

On the repair note (0eu) it said that my screen was replaced.

I had the same problems as in the OP.

Running beter then ever now.
[HD2 General] detroja:
No doubt, Tmobile attempts to be helpful. But, I consider HTC, as a manufacturer, to be well-prepared to deal with their own product's issues. If you have these problems repeatedly, I recommend you contact HTC directly. They may send you a new replacement instrument altogether. I had several positive surprises from HTC.
[HD2 General] wakedude:
HTC No Longer Repairs HD2

I know this is an old thread, but I have an HD2 with a digitizer that quit working that I wanted fixed. I just called HTC and was told that they have not been able to find a proper way to fix the phone and that they would not be able to repair it even if I paid them. This came from the customer service manager. Both the service rep and I were left without words. He couldn't believe that this was the response as he has never heard of such a thing. HTC has taken the HD2 out of their repair database. Seems pretty sketchy to me. Obviously they know about the problem and it sounds like they should issue a recall on the product if it consistently breaks on people with normal use and they have no way of repairing it.
[HD2 General] detroja:
HD2 screen not working

They fixed mine on Feb 22, 2011 for free under a warranty. I suggest you do not give them the diagnosis of digitizer is not working. Instead, just tell them the problems you have and let them tell you what is wrong with the phone.

If is going to cost an arm and a leg to fix the phone or a 1 month of outage from cellphone, I recommend you get a new phone from Craigslist or eBay. HD2 are dirt cheap now. Good luck.
[HD2 General] d34thw4lk3r:
hd2 is dead

Yep - i'm not surprised. I purposely bought the HD2 to get dual boot setup. Lasted two months and then screen stopped responding when screen locked. Eventually could not unlock at all. I stripped the phone, put in new screen and digitiser and new keypad buttons and then flashed back to original rom too.

GUESS WHAT??? STILL BUSTED.

So you can try many fixes found online, but I reckon once it busted don't waste your money just bin it.

SAD :(
[HD2 General] hengsheng120:
From what i've seen too, it is very difficult to actually repair the digitizer without causing new secondary problems. I paid my repair shop over 155 usd to repair an hd2 with usb and touchscreen problems and they just replaced the virtually the entire hd2 (mainboard+LCD+digitizer). And it still had problems in the end!
[HD2 General] bib*oops:
Interested in selling it?
[HD2 General] iamvoodoo:
i found a way

I did it all from sd card and got the rom from tmoble's website..simple once i got it down... if your IMEL# doesent work on current phone use the one on the new phone and download the rom fom tmoble.com ....... you will need 1 exta sd card (do not put in phone) put it in computer and format FAT32 standard......... extract the file you downloaded move the signed ruu file and copy to desktop rename (caps important) LEOIMG.nbh and copy to sd card ance done turn off your phone pull out old sim card put in new one poweron hold volume down...... loader should start... power button to stasrt proccess (takes 10-15 mins) phone will say complete open back cover and hit the master reset..... windows will pop up donezo!!!! i just did it for warranty on my phone with tmoble hope this helps others!
[HD2 General] takaros666:
Hallo!!!

I was having the same problem while i was using sd android but only with the touch

So i decided to install nand

when i set hspl3.03 form mistake and boot the windows 6.5 the touch worked perfect so i moved to install nand android with hspl 2.08 but at the end i was having the same problem

Is anyone know what to do because i am from greece and it is too expensive to send it to replace the screen

Thank you
[HD2 General] iamvoodoo:
hey dood, i had nand on my US tmoble HD2 touch screen went out, i have a few posts you should follow if you are going for warranty.

i had to download the software from the tmoble website..... You will need an IMEL number for this ...... or go and try to find your stock rom on the interwebs...... have a secondary SD card (not the one in your phone) follow the SPECIFIC steps and drop your new file on the new sd card and replace it with the one in your phone then follw normal booting steps in the tri color screen.,..... i do have a post that is a quck rundown with a little bit more info........ but the main thing is.... if you send it for warranty you have to put YOUR (country/carrier specific) stock rom on or they will fully charge you....... hope this helps....... other than that its a phone issue i belive its the screen digitizers.... so if not under warranty thats what it will cost to fix
